Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts

Book Synopsis Semiconductor Nanostructures by : Dieter Bimberg
Download or read book Semiconductor Nanostructures written by Dieter Bimberg and published by Springer. This book was released on 2010-11-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing the size of a coherently grown semiconductor cluster in all three directions of space to a value below the de Broglie wavelength of a charge carrier leads to complete quantization of the energy levels, density of states, etc. Such “quantum dots” are more similar to giant atoms in a dielectric cage than to classical solids or semiconductors showing a dispersion of energy as a function of wavevector. Their electronic and optical properties depend strongly on their size and shape, i.e. on their geometry. By designing the geometry by controlling the growth of QDs, absolutely novel possibilities for material design leading to novel devices are opened. This multiauthor book written by world-wide recognized leaders of their particular fields and edited by the recipient of the Max-Born Award and Medal 2006 Professor Dieter Bimberg reports on the state of the art of the growing of quantum dots, the theory of self-organised growth, the theory of electronic and excitonic states, optical properties and transport in a variety of materials. It covers the subject from the early work beginning of the 1990s up to 2006. The topics addressed in the book are the focus of research in all leading semiconductor and optoelectronic device laboratories of the world.
Book Synopsis Modeling and Simulations of Quantum Dots and Other Nanostructures by : Solmaz Torabi
Download or read book Modeling and Simulations of Quantum Dots and Other Nanostructures written by Solmaz Torabi and published by . This book was released on 2010 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: In microelectronic technology, there is a need to manufacture the next generation of smaller, faster, and efficient devices. However there are some fundamental that prevents making smaller devices. The use of self-assembly process to manufacture ordered semiconductor nanostructures such as quantum dots promises to be an inex- pensive and effective route to overcome size scale limitations in current fabrication processes. In crystalline films these nanostructures arise through instability originat- ing from a lattice misfit between film and substrate, from strong surface anisotropies or from kinetic surface fluxes. Producing such ordered nanostructure is still chal- lenging. A fundamental understanding of the self-assembly process during epitaxial growth is necessary to achieve controlled quantum scale structures. In this thesis, we study the influence of anisotropic surface and strain energies as well as continuous mass deposition on heteroepitaxial thin film growth by modeling means. There are different classical ways to model the anisotropic surface energy; however, they have mathematical and physical limitations. This motivated us to develop two new ways to model this energy. In the first method, the anisotropic surface energy multiplied to the isotropic CahnHilliard free energy. Our model contains a high-order Willmore regularization, where the square of the mean curvature is added to the energy, to remove the ill-posedness introduced by sharp corners. A key feature of this approach is the development of a new formulation in which the interface thickness is independent of crystallographic orientation. This makes the Willmore regularization compatible with the rest of the energy. Both numerically and analytically, we show the convergence of our phase field model to the general sharp interface model. In the second method, we develop an extended Cahn-Hilliard model. Incorporating high order terms in the energy, crystalline symmetries can be modeled naturally. For example to simulate Silicon, the diamond cubic symmetry is needed. Accordingly, terms involving 4th order derivatives are included in the energy. One advantage of this approach is its intrinsic regularized behavior. For this system, we develop an energy-stable scheme in which the energy decreases for any time step.

Book Synopsis Modelling of Semiconductor Nanostructures by : Boon Hon Hong
Download or read book Modelling of Semiconductor Nanostructures written by Boon Hon Hong and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: III-V semiconductor nanostructures are widely used in optoelectronic devices (e.g. lasers and detectors) in the visible (0.4-0.8 [mu]m), near-infrared (0.8-3 [mu]m), mid-infrared (3-5 [mu]m) and far-infrared (> 8 [mu]m) wavelength ranges, with great potential for high performance and high temperature operation. As well as simple designs, complex structures incorporating low dimensional components (e.g. quantum wells and quantum dots) are not unusual. Often, the optical and electronic characteristics of these structures are altered significantly as compared to bulk material. As a prerequisite to design for different applications, the study of their electronic and optical properties is essential. With the increasing computational power of modern personal computers, computational modelling becomes viable and more efficient. Indeed, it has become routine to follow (or to precede) experimental studies with computational modelling of good interpretive and predictive power. Combined with experimental studies, this is a powerful tool to provide insight into new devices. This research work is primarily based on calculations of the electronic band structure of various semiconductor nanostructures, followed by modelling of optical transitions and optical spectra. All numerical calculations use a cost effective computational method. The applicability of the model to ultra-thin structures of short period InAs/GaSb superlattices is investigated. The work is then extended to study complex quantum-dot-in-well structures. Finally, the attempt to extract the structural parameters of quantum dots by a combination of modelling and optical spectroscopy is presented.
